spotify-last-known

Tiny background service that:

1. Polls Spotify currently-playing
2. Persists the last known track to a local JSON file
3. Serves it publicly over HTTP (with CORS)

Setup

Create an .env (or export env vars) with:

• SPOTIFY_CLIENT_ID
• SPOTIFY_CLIENT_SECRET
• SPOTIFY_REFRESH_TOKEN

Optional:

• PORT (default: 9783)
• POLL_MS (default: 8000)
• STATE_PATH (default: ./data/last-known.json)

Run

npm i
npm start

Endpoints:

• GET /last-known -> persisted state JSON
• GET /healthz -> { ok: true }

Notes

• Intended for a single machine / single instance.
• JSON is written atomically using a temp file + rename.
